The US Army psychiatrist accused of opening fire on fellow soldiers in the deadliest such incident at a US military base took charge of his own defense on August 6, 2013 as his high-profile trial got underway. Major Nidal Malik Hasan, who has previously admitted killing 13 people and wounding 32 others in the 2009 attack at Fort Hood, faces the death penalty if convicted. Nearly four years after being attacked by one of their own in what should have been the safety of a protected base, survivors are steeling themselves to be cross-examined by Hasan, who has sacked his lawyers. The attack jolted the US military and prompted calls for stronger safeguards against possible internal security threats and "homegrown" terror attacks.
